,io all whom it may concern:

Be it known that I, FRANK L. HILL, a citizen of the United States, residing at Dayton, in the county of Campbell and State of Kentucky, have invented certain new and usefulilimprdvements-in Processes of lmitoting Unyx and Marble on Glass; and I do declare tlic following to be a full, clear, and exact description oiltbe invention, such as will enable others skilled in the art to which it ayperiaius to make and use the same.

1M iriveniion relates to a process of imitoting onyx and marble on glass. I

'lhe object of the invention is to produce an imitation of onyx or marble by applying, to the back or plate or other transparent glass, any desired combination of colors in the manner hereinafiter described and afterward specifically claimed.

In the accompauciiig' drawings: Figure 1 a front View oi a glass panel showing the application of my improved process for imitating onyx; Fig. 2 is a cross sectional View of the same; Fig. 3 is a front view of a glass panel showing the application of my improved grocessv for imitating 'verd marble. {in carrying out the invention 1 provide a piece of glass of the desired size and shape,

.eaid "glass being preferably though not uecessaiuly plateglass. 0n the back of the glass, which has been thoroughly cleaned,

1s first applied a coating or" linseed oil and varnish mixed in about equal parts and to wliioli is added a little Japan drier and in cool temperatures, a little turpentine may be added. After thus coating the glass a coating of colors is app ied by flowing upon the varnish coating bile still Wet.

l" preparing the color coat the desired colors are selected and mixed in the sonic composition of materials which form the first coat, it being understood that the colors areculy mixed suificiently to obtain the desired Variegation or onyx eliect and not to rneke an entirely opaque mixture. i Vheu thecolor has been thus mixed and is plied to the first coat before the latter has dried, the'color coat will soften and flow DQtO the first coat which produces a better trouspareney than if applied directly to the lass or upon dry coating. After the ioregoing steps of the erocess are corupleted, one or more coats of point are applied to the semi-transparent color coating to form a color backing, after which a finishing coat oi shellac is applied which forms a substantial backing or protection for the color work. An imitation of onyx or marble applied to glass in the iiiaimer described will have the deep and transparent e'dect of po l bed onyx or marble. By the agp glication of the color coating in the manner described the colors are free from atmospheric conditions and are protected against marririg or scratching and permit the outer surface of; the glass to be kept clean Without danger of injuring the color Work will, therefore last indefinitely,

Glass prepared in accordance with this ill" vention may be employed wherever onyx, or marble 15 used, such ior instance as on. Walls,-

and similar surfaces, and iii eounectiouwith bath room fixtures, bar fixtures, soda form; taius, store counters and the like. Haring thus described my invention *grliat I claim as new is: A

The hercindesoribed process of imiiatiug onyx or marble or: glass which consists 1o parent mixture upon the oil and varnish coat wbile the latter iss till wet, applying a color backing of coats of paint upon the ,variegated coat after the latter is dry, and

finally applying e protecting andfinishing v coating upon said backing In testimony whereof I liave hereunto set my band in presence of two subscribing Witnesses.
